Sardoria

It's all about the testing. Get at least three testers for your game, with a sufficient variety of approaches between them. Then, watch for the things they try. If they get close to the answer, your game should provide some appropriately encouraging feedback.

This is especially important in a game like Sardoria, where many of the puzzles are one kind of combination lock or another, most of whose combinations verge on the totally arbitrary. This is a subject that deserves a more detailed treatment, but I'm unable to do that in a spoiler-free review, so all I can say is that designers must anticipate the majority of player responses and handle them appropriately. It's a lot of work, yeah, but it can be the difference between exciting and exasperating for puzzly IF.
